Colorado sports betting soars past $2.3 billion in first year Keely Sugden, KDVR-TV · May 10, 2021 at 9:15 pm Colorado topped $2.3 billion in total wagers placed for the first year of legalized sports betting. The first bet was placed May 1, 2020. The state reached the $1 billion mark in December. “The first year of sports betting exceeded our expectations, especially after we launched amid a worldwide pandemic that shuttered the casinos, the industry, and Colorado,” said Division of Gaming Director Dan Hartman. “Looking back on a year ago, I don’t believe any of us expected to be where we are with our numbers and our operations.” Gross Gaming Revenues totals for the first year reached $148,103,448, with $2,325,477,052 (unaudited) total wagers between May 1, 2020, and April 30, 2021, according to the Colorado Department of Revenue.
